Abstract
The invention discloses a method for testing compression deformation of block rubber. The method comprises the following steps: (1) fixing block rubber to be tested on a machine table, and vertically and downwards extruding the block rubber by adopting an elastometer of which the front end is provided with a V-shaped mold head, so that one V-shaped dent deformation can be formed on the surface; (2) testing the V-shaped dent deformation, recording a deformation value V1, timing with a timer, testing the deformation of the rebounded block rubber after 1 minute, and recording a deformation value V2; (3) calculating the compression deformation according to a computational formula specified by standard: (C%)={(V1-V2)/V1}*100, so as to obtain the compression deformation of the block rubber, and comparing the compression deformations of different batches of rubber products so as to judge whether the rebound resilience of different batches of the rubber products meets the using requirement. The method has the advantages of convenience, simplicity, fastness and no damage to the sample.
Description
Technical field
The present invention relates to detection method, especially relate to a kind of convenient and simple, fast, can not destroy the assay method of the block rubber compression set amount of sample.
Background technology
All the rebound resilience of rubber material is had relatively high expectations for the rubber roll using in lithium battery process equipment and rubber cushion, but the rebound resilience of rubber (national entitling is called the compression set amount of rubber) is the value of a more difficult mensuration, if according to existing universal method, not only measure Fixture designing more complicated, but also need carry out destructive sampling sample preparation to measuring sample, its efficiency is lower, is not suitable for batch production inspection.
Summary of the invention
For addressing the above problem, the object of the invention be to provide a kind of convenient and simple, fast, can not destroy the assay method of the block rubber compression set amount of sample.
The present invention realizes by following technical measures, a kind of assay method of block rubber compression set amount, and it comprises the steps:
(1) determined block rubber is fixed on board, vertically downward block rubber is pushed with the elastometer that a front end is provided with a V-type die head, make its surface form 1 V-type indenture deflection;
(2) immediately V-type indenture deflection is measured, recorded its deformation values V1, clock with timer, wait for that 1min measures the deflection after block rubber resilience above again, record its deformation values V2;
(3) computing formula of establishing criteria regulation is calculated compression set amount (C%)={ (V1-V2)/V1 } * 100, can obtain the compression set value of tested block rubber, and the compression set amount that is worth contrast different batches rubber product with this, judge whether the rebound resilience of the rubber product of each batch meets request for utilization.
As a kind of optimal way, described block rubber is sheet shape or cylindrical.
As a kind of optimal way, the angle of described V-type die head is 60 degree.
As a kind of optimal way, described elastic force is designated as 10kg elastic force note.
As a kind of optimal way, described deflection uses dial test indicator to measure.
Measuring method of the present invention has been because only having utilized little frock clamp, therefore simple in structure, accuracy is high, can not destroy sample simultaneously, be applicable to check in batches and use.
